Well I sure hope it's not a symptom of anything serious since some of my plants are way more curled.

I think your chili is just fine, the curling will ease when the plant gets bigger. EC 2.2 sounds a bit high (to me, I use way lower dosage) but if it grows and doesn't show signs of OD you should be fine.

That could be the result of too low/high pH, in this case too low. The EC may be a little too high for young plants as well but I don't think you should change anything yet. The plant looks very healthy and it seems to be a big one too. I don't think you have anything to worry about for now!

Thanks for the reply's!I just checked the plant outside of the tent.I've noticed some yellow/lightgreen spekkles on the older leaf.Maybe a slight Magnesium deficiency?I think the plant doubled in size since my last post!!Unbelievable fast growth compared to the other ones.Btw it's an Fatalii Red
